Our Journey
WMM Construction was founded to build on more than a decade of proven experience in the construction industry. Our leadership team previously operated under Skystone, where we delivered some of the most complex modular and multifamily projects in North America — including a 20-story modular hotel in New York City.
Today, WMM continues that legacy with the same experienced leadership, technical expertise, and commitment to quality that has defined our work since 2014. As a licensed General Contractor in California, we bring deep expertise in multifamily, modular, and electrical construction to every project we undertake.
Trusted by Developers for Complex Builds
WMM stands apart through a rare blend of technical expertise and hands-on execution. From managing high-rise modular hotels to self-performing critical electrical scopes, our team brings real-world capability to every job. Clients trust us because we’ve done it — and delivered.
